An ever-increasing incidence of skin neoplastic diseases is registered. Therefore, it is important to protect the skin from the UV radiation that reaches the epidermis and dermis but also to block ROS generated by them. Our attention was attracted in developing new compounds provided with both UV...

摘要: Sulfobacin A (flavocristamide B, 1), sulfobacin B ( 2), and flavocristamide A ( 3), biologically active sulfonolipids, have been efficiently synthesized utilizing the asymmetric aldol reaction of the Schiff base 8 derived from glycine ester and (+)-2-hydroxy-3-pinanone (HyPN)....
of 1 M HCl was assessed via electrochemical methods and loss in weight. FT-IR,1H-NMR spectra and elemental analysis were used to confirm the structure of such compounds. It was found to have successful inhibition even at low concentrations in tested media, as an increase in inhibitor ...
